A list has been compiled of the five top games that were released during 2011.

Microgaming’s all round slot game, Gold Factory, was listed as No. 1. The slot game has 50 pay-lines and is themed on a Willie Wonka type of gold factory. Gold Factory offers a bonus feature called the Boiler Room Bonus during which players get to win between 10 and 35 spins by finding the Free Spins symbol with all prizes doubled.

Cryptologic’s Horns & Halos was listed as No. 2. Players need to choose one of two sets of three reels, one representing Hell and the other Heaven, that spin simultaneously for the payouts.

Playtech’s branded slot game, Kong, is listed as No. 3 and is based on the Universal Studios movie that features King Kong. The slot game includes characters and scenes from the movie.

Microgaming’s blockbuster game, titled Immortal Romance, is No. 4 on the list. The slot game features beautiful graphics and offers a haunting original soundtrack. Immortal Romance introduces players to a curious cast of four characters. Players have a chance to bet from 0.30 to a maximum of 6.00 a line in this slot game that provides players with an immersive gaming experience. Immortal Romance may have moved up on the list if the slot game had extended the features of Thunderstruck II on which it is based.

WagerWorks’ Siberian Storm has a MultiWay Xtra Feature with an unusual structure. The slot game offers very lucrative free spins features and offers players 720 ways to win.
